SPECIFICATION forming part of Letters Patent No. 447,694, dated March 3, 1891. Application filed March 27, 1890. Renewed January 22, 1891- `Serial No. 378,678. (No model.)

, To all whom 1115 may concern:

Be it known that I, LOUIS N. MOSIER, a eitizen of the United States of America, residingat Harlem, in the county of Clay and State of Missouri,haveinventedcertainnewandusefullm- :proveniente in Detector-Bars; andI do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to' the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My improvement@` relate to detector-bars which are employed to detect the presence of a car or cars upon a railway-track and operate switches.

The object ofthe invention is to provide means whereby a detector-bar can be readily attached to a rail of ordinary eonstruction,so

' that all the parts thereof will be located above thel ties or lower edge of the rail, and which can be attached to the rail without displacing the same; and 'it consists in providing a block which is adapted to be rigidly secured to the web of the rail by means of a bolt, said bleek also carrying a bolt to which one end of links or arms is pivoted, while] the opposite ends are pivotally secured to the bar, the parts being organized so that when the detector-bar is lowered it will rest upon the heads of the v bolts which secure the blocks to the rails, and

when elevated will be inclined, so that the upper edge of the detector-bar will be over the tread of the rail, so as to be positively acted upon by the car-wheels.

In the accompanying drawings, Figure l is a longitudinal elevation or side view, the detector-bar being shown lowered in full lines and elevated in dotted lines. Figs. 2 and 3 are vertical section al views taken through the lines :t and yy, respectively, of Fig. l. Fig. ltis a detail perspective view of the supporting-block detached.

A refers to the railroadrail, which is of ordinary construction and is provided at suit-- able points with perforations or openings c,

through whichpass bolts B for securing the blocks C in place. The boltB is screw-threaded at one end, while the opposite end has a rectangular head formed thereon, the sides of which project from the body of the bolt, and

the lower end depends, leaving the upper edge of said head substantially on a line with the shank. This is a desired construction, as upon the upper edge of the head of the bolt the detector-bar will rest when down.

The bleek C has on its outer surface or iuelined edge a recess b, within which a portion of the head of the bolt B will lie, this recess not only preventing the rotation of the head of the bolt, but also forming a bearing for the same. This block is provided at its ends with projections which conform to the shape of the rail and provides a space in which the head of the bolt D may lie, as well as lightening the block.

The belt D is provided adjacent tothe outer inclined surface of the block C with a Washer.

or ring (l, and next to this ring lie the arms or links E, said links moving/,freely'upon the bolt l), and are secured thereto by a washer and pin. To the outer ends of the links E is secured the detector-bar F by bolts d', which pass through the linksand are secured thereto by a pin or nui..

The detector-bar has attached thereto at a suitable pointan outwardlyprojecting pin G, to which the connecting-rod is attaehed,wl1ich leads to levers or other devices for operating the switch or other mechanism for locking the switch when the ears are upon the track, or for other purposes for whichdetector-bars are usually employed.

The detector-har when depressed may not only rest upon the bolts l), bu t, if desired, /ean also have a bearing upon the washersd, and i it will be observed that by the construction and arrangement of the parts herein shown the outer edges of the blocks are at an inclination with the web of the rail, as well as the operating parts, so that when the detector-bar is raised ,it will be moved over the tread of the rail to be positively acted upon by the ear-wheels.

I am aware that prior to myinvention adetector-bar has been pivoted to links orarrns, so that it will be moved when raised atan inclination with the rail, and I do not claim such construction,broadly; but

W hat l claim as new, and desire to secure by Letters Patent, is-

l. The combination, with a railroad-rail, of recessed blocks secured to the web of the IOO rail by. bolts B, said blocks having outwardly and upwardly inclined bolts D, upon which are pivotod links or arms E, and a detector-bar secured to the upper ends of said arms, the bolts ll serving the two fold purpose of holdings,r the blocks C to the rails and as stops for the detector-bar, substantially as set forth.

L. In combination with a railroad rail, blocks C, having their ends shaped to eonforni to the rail, bolts 13 for securing said blocks in place, upwardly-inclined bolts D, secured to the blocks, links loosely pivoted thereon, and n detector-bar having upwardlyinolined projections or bolts d for attaching the upper ends of the links thereto, substantially as Set forth.

il. rlhe combination, with a railroad-rail,of blocks C, having inclined recesses li,horizou tal belts l5 for ser-ming said. blocks to the rail, said bolts having rectangular heads adapted to partirlly lie u itliin the recesses l), bolts or pintles L Seemed lo the blocks C at an upward inclination, washers d, and links E, pivotally mounted on the boltsD and pivotally connected to the detector-bar, so that when the detector-bar is Ielevated the upper edge thereof will be over the edge of the rail and when lowered will rest upon the projecting heads of the bolts li, substantially as shown, and for the purpose set forth.

In testimony whereof 1 ailix mysignatu re in presence of two witnesses.
